Optimization of Bellis & Morcom 3rd-stage piston ring CBM model
This report is an evaluation of EXAKT at a steel mill. The discussion focuses on data collection and manipulation. A brief discussion on the capability and usefulness of EXAKT is also included in the conclusion. The objective was to determine whether EXAKT could be effectively utilized in a commercial manufacturing environment to improve the results obtained with current (PM) models.

Optimizing condition-based maintenance decisions for vibration monitored bearings
We report the development of an optimal maintenance program based on vibration monitoring of critical bearings on machinery in the food processing industry. Statistical analysis of vibration data is undertaken using the software package EXAKT to establish the key vibration signals that are necessary for risk estimation.

CBM (on-condition maintenance) benefits analysis
We should compare the cost effectiveness of an existing maintenance policy with that of a proposed new one, in order to project the benefits of proceeding with that proposed policy. By a policy in CBM we mean, how we will define and declare a potential failure...

Optimizing a Condition Based Maintenance Program with Gearbox Tooth Failure
The EXAKT CBM optimizing methodology was applied to a set of experimental condition data measurements in order to develop an optimal interpretation process or policy. An optimal policy is a procedure for data interpretation, which, if applied consistently in a CBM program, minimizes the cost of maintenance of a physical asset or maximizes its availability...

Can RCM (Reliability Centered Maintenance) and Streamlined RCM peacefully co-exist?
Religious or political zealots confront one another, often, not on the basis of the mores of their respective doctrines, but rather from the superficial differences in the details surrounding each other's cultural reference points...

Thinking RCM ( Reliability Centered Maintenance)
When attempting to maintain a large industrial facility we face a complex challenge. We search yet rarely discover a single silver bullet capable of subduing the beast.

Why PHM? Incorporating Covariates in Weibull Analysis
Low failure probabilities are critical factors in business decisions when high costs are incurred due to the consequences of failure. In these circumstances intensive data analysis efforts are employed to assess probabilities of failure. Weibull analysis is commonly used to analyze data, especially in cases where the propensity of failure increases with time and use...

CBM Optimization
What do we mean by CBM (condition based maintenance) optimization? We mean, simply, how to "correctly" interpret and act upon data from our condition monitoring (CM) program. Is the decision to act, and the action itself the "right" one? The "best" one? How do we define "best"? What does the "best" time and action depend on?

A History of CBM (condition based maintenance)
Physical asset managers attempt to implement policies that maintain the functionality of machinery and other production assets at a level required by their users, owners, and by society at large. They select "proactive maintenance" as their first line of defense against causes of equipment failure.

CBM (Condition Based Maintenance) Expert Systems
A rule-based expert system encapsulates known relationships between CM data and the deterioration in an asset that takes place due to one or more failure modes. An algorithm (known as inference engine) applies the knowledge base to the current set of CM data.
